Elizabeth Ann
Elizabeth Ann (born December 10, 2020) is a black-footed ferret, the first U.S. endangered species to be cloned. The animal was cloned using the frozen cells from Willa, a black-footed female ferret who died in the 1980s and had no living descendants. The cloning process was led by Revive & Restore, a biodiversity non-profit. Background Black-footed ferrets are the only ferret species native to the United States. The black-footed ferret is one of the most endangered and rarest land mammals in North America; a small pack of them was found in Wyoming in 1981. The limited genetic diversity found among the pack put the species at risk. Scientists sent genetic material from Willa to San Diego Zoo’s Frozen Zoo in 1988. Willa's egg was implanted in a surrogate domestic ferret in November 2020, to avoid putting an endangered ferret at risk. Elizabeth Ann was delivered via c-section on December 10. Life Elizabeth Ann will live in Colorado and be studied for scientific purposes; she w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-footed Ferret
The black-footed ferret (''Mustela nigripes''), also known as the American polecatHeptner, V. G. (Vladimir Georgievich); Nasimovich, A. A; Bannikov, Andrei Grigorovich; Hoffmann, Robert S. (2001)''Mammals of the Soviet Union''Volume: v. 2, pt. 1b. Washington, D.C. : Smithsonian Institution Libraries and National Science Foundation. or prairie dog hunter, is a species of mustelid native to central North America. The black-footed ferret is roughly the size of a mink and is similar in appearance to the European polecat and the Asian steppe polecat. It is largely nocturnal and solitary, except when breeding or raising litters. Up to 90% of its diet is composed of prairie dogs. The species declined throughout the 20th century, primarily as a result of decreases in prairie dog populations and sylvatic plague. It was declared extinct in 1979, but a residual wild population was discovered in Meeteetse, Wyoming in 1981. A captive-breeding program launched by the United States Fish an ...

Carr, Colorado
Carr is an unincorporated community that used to have a U.S. Post Office in Weld County, Colorado, United States. The ZIP Code of Carr is 80612. Some consider Carr a ghost town. Today, a few old houses remain plus a church and the schoolhouse, but the old store fronts are gone. There are some scattered old foundations throughout the town. There are a growing number of year-round residents, so the town no longer appears abandoned. History The town of Carr was established by the Union Pacific Railroad in 1872. Carr was named for Robert E. Carr of the Union Pacific, who managed the construction of the rail line through the town. The Carr, Colorado, post office opened on March 26, 1872. From 1920 until 1939, the town carried Old Colorado State Highway 5, which was meant as an access route. However, during this time, routes numbered 1–19 were major cross state highways, making it a somewhat useless route. The U. S. Post Office was closed circa 2021 when the privately owned buil ...

Cloning
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of Cell (biology), cells and of DNA fragments. The artificial cloning of organisms, sometimes known as reproductive cloning, is often accomplished via somatic-cell nuclear transfer (SCNT), a cloning method in which a viable embryo is created from a somatic cell and an egg cell. In 1996, Dolly (sheep), Dolly the sheep achieved notoriety for being the first mammal cloned from a somatic cell. Another example of artificial cloning is molecular cloning, a technique in molecular biology in which a single living cell is used to clone a large population of cells that contain identical DNA molecules. In bioethics, there are a vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revive & Restore
Revive & Restore is a non-profit wildlife conservation organization focused on use of biotechnology in conservation. Headquartered in Sausalito, California, the organization's mission is to enhance biodiversity through the genetic rescue of endangered and extinct species. The organization was founded by Stewart Brand and his wife, Ryan Phelan. Revive & Restore has created a "Genetic Rescue Toolkit" for wildlife conservation – a suite of biotechnology tools adapted from human medicine and commercial agriculture that can improve wildlife conservation outcomes. The toolkit includes biobanking and cell culturing, genetic sequencing, and advanced reproductive technologies, such as cloning. The toolkit complements traditional conservation practices, such as captive breeding and habitat restoration. Revive & Restore has caused controversy. In particular, Brand's work in de-extinction has been characterized as "playing god" and criticized for taking time and money away from traditi ...

San Diego Zoo Global
The San Diego Zoo Wildlife Alliance is a nonprofit organization headquartered in San Diego, California, that operates the San Diego Zoo and the San Diego Zoo Safari Park. Founded in 1916 as the Zoological Society of San Diego under the leadership of Harry M. Wegeforth, the organization claims the largest zoological society membership in the world, with more than 250,000 member households and 130,000 child memberships, representing more than half a million people. The San Diego Zoo and San Diego Zoo Safari Park feature a combined 15,000 animals of 750 species, not all of which are displayed publicly. In its first few decades, the Zoological Society of San Diego worked to establish and build up the San Diego Zoo. Members of the organization formed groups that later became the Association of Zoos and Aquariums (AZA) and American Association of Zoo Keepers (AAZK). In the early 1970s the society established the San Diego Wild Animal Park and the Center for Reproduction of Endangered S ...

Caesarean Section
Caesarean section, also known as C-section, cesarean, or caesarean delivery, is the Surgery, surgical procedure by which one or more babies are Childbirth, delivered through an incision in the mother's abdomen. It is often performed because vaginal delivery would put the mother or child at risk (of paralysis or even death). Reasons for the operation include, but are not limited to, obstructed labor, twin pregnancy, pre-eclampsia, high blood pressure in the mother, breech birth, shoulder presentation, and problems with the placenta or umbilical cord. A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section. A trial of Vaginal birth after previous C-section, vaginal birth after C-section may be possible. The World Health Organization recommends that caesarean section be performed only when medically necessary. A C-section typically takes 45 minutes to an hour. It may be done with a spinal block, where the woman is awake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captive Breeding
Captive breeding, also known as captive propagation, is the process of keeping plants or animals in controlled environments, such as wildlife reserves, zoos, Botanical garden, botanic gardens, and other Conservation biology, conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, Habitat fragmentation, fragmentation, overhunting or fishing, pollution, predation, disease, and parasitism. For many species, relatively little is known about the conditions needed for successful breeding. Information about a species' reproductive biology may be critical to the success of a captive breeding program. In some cases a captive breeding program can save a species from extinction, but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hysterectomy
Hysterectomy is the surgical removal of the uterus and cervix. Supracervical hysterectomy refers to removal of the uterus while the cervix is spared. These procedures may also involve removal of the ovaries (oophorectomy), fallopian tubes ( salpingectomy), and other surrounding structures. The term “partial” or “total” hysterectomy are lay-terms that incorrectly describe the addition or omission of oophorectomy at the time of hysterectomy. These procedures are usually performed by a gynecologist. Removal of the uterus is a form of sterilization, rendering the patient unable to bear children (as does removal of ovaries and fallopian tubes) and has surgical risks as well as long-term effects, so the surgery is normally recommended only when other treatment options are not available or have failed. It is the second most commonly performed gynecological surgical procedure, after cesarean section, in the United States. Nearly 68 percent were performed for conditions such as ...

Uterine Horn
The uterine horns (cornua of uterus) are the points in the upper uterus where the fallopian tubes or oviducts exit to meet the ovaries. They are one of the points of attachment for the round ligament of uterus (the other being the mons pubis). They also provide attachment to the ovarian ligament, which is located below the fallopian tube at the back, while the round ligament of uterus is located below the tube at the front. The uterine horns are far more prominent in other animals (such as cows and cats) than they are in humans. In the cat, implantation of the embryo occurs in one of the two uterine horns, not the body of the uterus itself. Occasionally, if a fallopian tube does not connect, the uterine horn will fill with blood each month, and a minor one-day surgery will be performed to remove it. Often, people who are born with this have trouble getting pregnant as both ovaries are functional and either may ovulate. The spare egg An egg is an organic vessel grown by a ...
